What is the primary function of floral foam?

The primary function of floral foam is to provide support and hold flowers securely in place. This specialized material is designed to absorb water and hold it, which helps keep the flowers hydrated while also allowing for better arrangement stability. When fresh cut flowers are inserted into floral foam, they can maintain their positions effectively, making it easier for the florist to create visually appealing designs. The foam's structure supports the stems and ensures that arrangements can be both aesthetic and practical, allowing for longer-lasting floral displays.

Color or the addition of pesticides are secondary aspects and not the core purpose of floral foam, while keeping flowers dry contradicts the need for hydration essential to floral arrangements.
